Hello :
<span>f(x)=x²+4x-5
</span><span>The axis of symmetry for a function in the form f(x)=x^2+4x-5 is x=-2 :
</span>f(x) = (x+2)² + b
f(x) x²+4x+4+b= x² +4x-5
4+b= -5
b = -9
the vertex is : (2 , -9)
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable. Exact Form: x = 38/7 Decimal Form: x = 5.428571 Mixed Number Form: x = 5 3/7

Answer:
u1 = 1
u6 = 31
un = 1 + 6(n - 1)
Step-by-step explanation:
Sn = 3n² - 2n
u1 = S1
3(1)² - 2(1)
3 - 2
1
u6 = S6 - S5
[3(6)² - 2(6)] - [3(5)² - 2(5)]
96 - 65
31
un = a + (n - 1)d
u6 = a + 5d
31 = 1 + 5d
5d = 30
d = 6
un = 1 + 6(n - 1)
Answer: 2460 calories
Step-by-step explanation:
2129 + 2348 + 1863 = 6340
2200 x 4 = 8800
8800 - 6340 = 2460
